Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more particularly to an electrical connector and kit that provides a communication path between electronic devices and accessory devices. Background Technology

[0002] Electrical connectors can be used for coupling between a variety of electronic and accessory devices. The plug connectors of these electrical connectors achieve mating by coupling the socket connectors of the mating electronic devices to the plug interface.

[0003] To standardize the connection and communication between electronic devices and accessory devices, electronic device manufacturers often use plug and socket connectors of the same standard. This means they produce different models and types of electrical connectors or electronic devices with the same appearance. On the one hand, this makes it difficult for users to effectively identify the compatible connector among the many electrical connectors used daily. Furthermore, users face the challenge of connecting multiple models of the same type of electronic device to accessory devices with identical shapes but different parameters, further increasing the difficulty of connector identification and impacting the user experience. On the other hand, inserting the plug of an electrical connector into the socket of an incompatible electronic device not only affects the normal operation of the accessory device and provides a poor user experience, but also poses an unpredictable risk of damage to the plug and socket connectors, such as pin bending.

[0017] The configuration of the foolproof part of any of the plug connectors is different.

[0018] This utility model provides an electrical connector and kit for providing a communication path between an electronic device and an accessory device. The electronic device has a foolproof opening, and the electrical connector includes a plug connector. One end of the electrical connector is electrically connected to the accessory device, and the other end is electrically connected to a socket connector of the electronic device via the plug connector.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] Figure 1 This is a schematic diagram of the structure of an electrical connector that provides a communication path between electronic devices and accessory devices, according to an embodiment of this utility model. Figure 2 This is a schematic diagram of another electrical connector that provides a communication path between electronic devices and accessory devices, according to an embodiment of the present invention. Figure 9 This is a structural schematic diagram of the accessory device of the electrical connector of the first type of electrical connection provided in this utility model embodiment. Figure 10 This is a structural schematic diagram of an accessory device for another type of electrical connector provided in this embodiment of the utility model. Figure 11 This is an adaptable connection provided by the embodiments of this utility model. Figure 9 and Figure 10 The diagram shows an electronic device with two different socket connector perspectives, as shown. Figure 1 , 2 As shown in Figures 9, 10, and 11, electronic device 30 has a foolproof notch 311, and electrical connector 10 includes a plug connector 11, one end of which is connected to accessory device 20. Figure 9 , 10(As shown) Electrical connection, the other end is adapted to be electrically connected to the socket connector 31 of the electronic device 30 via a plug connector 11. The plug connector 11 includes: a housing 111, the housing 111 having a foolproof part 112 extending along its outer surface and corresponding to a foolproof notch 311, the foolproof part 112 being inserted into and pressed against the foolproof notch 311 in the mating direction to realize a mating event; a wing 12, the wing 12 having a first surface 1211 and a second surface 1221; and a plurality of first electrical contacts 1212 carried on the first surface 1211 of the wing 12, and a plurality of first electrical contacts 1212 carried on the first surface 1211 of the wing 12, and a plurality of first electrical contacts 1212 carried on the first surface 1211 of the wing 12. The connector 10 includes a plurality of second electrical contacts 1222 carried on the second surface 1221. Each of the plurality of first electrical contacts 1212 is electrically connected within the wing 12 or housing 111 to each corresponding electrical contact among the plurality of second electrical contacts 1222. The connector 10 also includes a circuit coupled to at least a portion of the plurality of first electrical contacts 1212 and at least a portion of the plurality of second electrical contacts 1222. The circuit includes a first identification feature element 151 and is used to enable the electronic device 30 to identify the accessory device 20 at a first level via the first identification feature element 151 after a docking event. It should be noted that the circuit may be specifically embodied in its carrier (PCB board 15), and the first identification feature element 151 is electrically connected on the PCB board 15.

[0038] First, it should be noted that the electrical connector 10 in this embodiment can provide a communication path between the electronic device 30 and the corresponding accessory device 20. For example, one end of the electrical connector 10 is electrically connected to the electronic device 30, and the other end of the electrical connector 10 is electrically connected to the corresponding accessory device 20, so that the electronic device 30 can be configured to control the operation or running of the corresponding accessory device 20, and the accessory device 20 can also transmit its own data to the corresponding electronic device 30 for analysis or storage.

[0039] Specifically, the electronic device 30 has a foolproof notch 311, and includes a socket connector 31, while the electrical connector 10 includes a plug connector 11. The housing 111 of the plug connector 11 has a foolproof part 112 extending along its outer surface. The foolproof notch 311 and the foolproof part 112 are correspondingly provided. Only when the structures of the foolproof notch 311 and the foolproof part 112 match can the plug connector 11 of the electrical connector 10 and the socket connector 31 of the electronic device 30 be mated; that is, the plug connector 11 of the electrical connector 10 can be inserted into the socket connector 31 of the electronic device 30. Figure 1 and Figure 3 As can be seen in the example, the four corners of the cross-section of the anti-fouling part 112 have recessed openings 13, corresponding to which in Figure 12 The foolproof notch 311 at the socket connector 31 on the left side has a matching structural design. Correspondingly, in Figure 2 and Figure 5 As can be seen in the example, the anti-fouling part 112 has two openings 13 at the top and bottom of the illustrated view, corresponding to the... Figure 12 The foolproof notch 311 at the right-side socket connector 31 has a matching structural design. It is understandable that, based on the structural foolproof matching between the foolproof part 112 and the foolproof notch 311, the structure of the foolproof notch 311 and the foolproof part 112 can also be other shape-matching structures, which will not be described in detail here.

[0040] In a more easily understood way, under the condition that the structure of the anti-fooling port 311 and the anti-fooling part 112 are matched, the anti-fooling part 112 can be inserted into and pressed against the anti-fooling port 311 along the mating direction to realize a mating event, which indicates the realization of the electrical connection between the electrical connector 10 and the electronic device 30. That is, the anti-fooling part 112 can be inserted into the corresponding anti-fooling port 311 along the direction of the insertion and removal axis 01, and can also be pulled out from the corresponding anti-fooling port 311 along the direction of the insertion and removal axis 01. One end of the electrical connector 10 is electrically connected to the socket connector 31 of the electronic device 30 through the plug connector 11, and the other end of the electrical connector 10 is electrically connected to the accessory device 20. In this way, a communication path is established between the electronic device 30 and the corresponding accessory device 20, enabling the transmission of signals and / or power between them; the electronic device 30 can also exchange information with the corresponding accessory device 20, for example, the electronic device 30 can read the serial number information of the chip (i.e., the first identification characteristic element 151) in the corresponding accessory device 20. This embodiment does not limit the electrical connection form between the electrical connector 10 and the accessory device 20. For example, the other end of the electrical connector 10 and the accessory device 20 can be an integral electrical connection structure, or the other end of the electrical connector 10 and the accessory device 20 can also form a pluggable electrical connection relationship through another matching plug connector 11 and socket connector 31.

[0041] And, continue to refer to Figure 1-6The plug connector 11 includes a housing 111 and a flap 12. Exemplarily, the housing 111 is typically a structure that a user holds when inserting or removing the electrical connector 10 from the corresponding receptacle connector 31. Exemplarily, the housing 111 may be made of a dielectric material. Exemplarily, the housing 111 may have a generally rectangular cross-section, or it may have a rectangular cross-section with rounded or angled edges, a circular cross-section, an elliptical cross-section, and many other suitable shapes. The flap 12 can be understood as a portion extending longitudinally away from the housing 111 along the mating direction (or along a direction parallel to the length of the housing 111). In the mating direction, one end of the housing 111 is a fixedly connected flap 12 (the end face of the housing 111 where it intersects with the flap 12 can be understood as a stop surface 14), and the other end of the housing 111 is a fixedly connected first wire 16. That is, one end of the plug connector 11 is electrically connected to the socket connector 31 of the corresponding electronic device 30 via the flap 12, and the other end of the plug connector 11 is electrically connected to the corresponding accessory device 20 via the first wire 16. Although Figure 1 and Figure 2 Although not shown, a portion of the structure of the wing 12 and a portion of the structure of the first wire 16 may extend within and be surrounded by the housing 111. Furthermore, by way of example, the wing 12 may be made of various materials including metals, dielectrics, or combinations thereof.

[0042] Furthermore, the dimensions of the wing 12 can be designed to be inserted into the socket connector 31 of the corresponding electronic device 30 during a docking event. The wing 12 has a first surface 1211 and a second surface 1221 that are parallel (or approximately parallel) and correspondingly arranged. A plurality of first electrical contacts 1212 are carried on the first surface 1211 of the wing 12, and a plurality of second electrical contacts 1222 are carried on the second surface 1221 of the wing 12. Exemplarily, the number of first electrical contacts 1212 is the same as the number of second electrical contacts 1222, and the orthographic projections of the first electrical contacts 1212 on the first surface 1211 and the orthographic projections of the second electrical contacts 1222 on the first surface 1211 correspond one-to-one and overlap. Exemplarily, these electrical contacts can be classified as data contact points. Exemplarily, the shapes of the first electrical contacts 1212 and the second electrical contacts 1222 can be square, circular, leaf spring, or cantilever beam, etc. This embodiment is merely an example and is not limited thereto. Exemplarily, in one specific embodiment, Figure 3 and Figure 5Each of the first electrical contacts 1212 shown is located on the same side of the first surface 1211, and each of the first electrical contacts 1212 is located on the side of the first surface 1211 closer to the second surface 1221. Similarly, each of the second electrical contacts 1222 is located on the same side of the second surface 1221, and each of the second electrical contacts 1222 is located on the side of the second surface 1221 closer to the first surface 1211. In another specific embodiment, Figure 4 and Figure 6 Each of the first electrical contacts 1212 shown is located on the same side of the first surface 1211, and each of the first electrical contacts 1212 is located on the side of the first surface 1211 away from the second surface 1221. Each of the second electrical contacts 1222 is located on the same side of the second surface 1221, and each of the second electrical contacts 1222 is located on the side of the second surface 1221 away from the first surface 1211.

[0043] These electrical contacts may be raised, recessed, or flush with the outer or inner surface of the flap 12, and each of the plurality of first electrical contacts 1212 is electrically connected within the flap 12 or housing 111 to each corresponding contact of the plurality of second electrical contacts 1222, such that when the flap 12 is inserted into the corresponding socket connector 31, these electrical contacts can be electrically coupled to the corresponding electrical contacts in the socket connector 31 to facilitate a communication electrical connection between the electrical connector 10 and the electronic device 30. In some embodiments, these electrical contacts may be self-cleaning wiping contacts, which, after initially contacting the corresponding electrical contacts in the socket connector 31 during a mating event, further slide across the electrical contacts in the socket connector 31 by a wiping motion before reaching the final desired contact position. Exemplarily, these electrical contacts may be made of copper, nickel, brass, stainless steel, metal alloys, or any other suitable conductive material or combination of conductive materials. For example, a first electrical contact 1212 can be printed on the first surface 1211 of the flap 12, and a second electrical contact 1222 can be printed on the second surface 1221 of the flap 12, using a technique similar to that used for printing contacts on a printed circuit board. For example, these electrical contacts can be formed by imprinting from a lead frame, which is located on the first surface 1211 and the second surface 1221 of the flap 12, respectively, and is surrounded by a dielectric material.

[0044] In other embodiments, one or more grounding contacts may also be formed on the third and fourth surfaces of the flap 12, wherein the third surface of the flap 12 (not shown) can be understood as one side connecting the first surface 1211 and the second surface 1221, and the fourth surface of the flap 12 (not shown) can be understood as the other side connecting the first surface 1211 and the second surface 1221. Each of these grounding contacts may be formed on the exterior of its respective side or constitute part of the exterior of its respective side. Exemplarily, these grounding contacts may be formed within a pocket, indentation, cut, or similar recessed area formed on each of the third and fourth surfaces of the flap 12, and / or these grounding contacts may be formed as part of a pocket, indentation, cut, or similar recessed area formed on each of the third and fourth surfaces of the flap 12, as detailed below, such that the formed pocket, indentation, cut, or similar recessed area can operatively engage with a retaining mechanism in the corresponding socket connector 31.

[0045] like Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 All the electrical connectors 10 shown include circuitry, which can be specifically represented by their carrier (PCB board 15), but Figure 7 The first surface 1211 and the second surface 1221 of the wing 12 shown are the inner surfaces of the upper and lower surfaces of the wing 12. Figure 8 The first surface 1211 and the second surface 1221 of the wing 12 shown are the outer surfaces of the upper and lower surfaces of the wing 12. In one specific embodiment, Figure 3 , Figure 5 and Figure 7 The wing 12 structure shown can be a Type-C interface. Figure 4 , Figure 6 and Figure 8 The wing 12 structure shown can be a Lightning interface. The common feature of the two wing 12 structures is that they can be plugged in and out in both directions. This embodiment is only an example and is not limited. Of course, the structure of the wing 12 can also be adapted and prepared by those skilled in the art.

[0046] The circuit in the electrical connector 10 can be coupled to at least a portion of the plurality of first electrical contacts 1212 and at least a portion of the plurality of second electrical contacts 1222. In other words, the first electrical contacts 1212 on the first surface 1211 of the wing 12 can be electrically connected to the corresponding second electrical contacts 1222 on the second surface 1221 of the wing 12 through the circuit. Thus, the socket connector 31 of the electronic device 30 can be electrically connected sequentially via the corresponding first electrical contacts 1212 (or second electrical contacts 1222), the circuit, and the second electrical contacts 1222 (or first electrical contacts 1212), and obtain the characteristic information of the circuit, such as relevant identifiers, serial numbers, models, manufacturer IDs, etc. In one specific embodiment, the circuit (PCB circuit board 15) includes a first identification characteristic element 151, which can be used to achieve the first level of identification of the accessory device 20 by the electronic device 30 after a docking event. In a more easily understood way, the electronic device 30 can obtain the characteristic information of the first identification characteristic element 151 in the corresponding circuit to determine whether the electronic device 30 itself matches the accessory device 20 electrically connected to the electrical connector 10. For example, the electronic device 30 can store a set of characteristic information and compare the obtained characteristic information with the stored set of characteristic information to determine whether the electronic device 30 itself matches the accessory device 20 electrically connected to the electrical connector 10. For example, the circuit and the first identification characteristic element 151 store characteristic information matching the electronic device 30 and the accessory device 20. For different accessory devices 20, the characteristic information of the circuit and the first identification characteristic element 151 in the corresponding electrically connected electrical connector 10 are different, so as to more accurately and quickly identify the matching relationship. For example, the circuit and the first identification characteristic element 151 can be a single circuit element, a small integrated circuit, etc.

[0047] In addition, continue to refer to Figure 7 and Figure 8 The first identification feature element 151 can be disposed on the PCB circuit board 15. The PCB circuit board 15 may also include solder joints 153, which can be electrically connected to the first conductor 16, thereby realizing the electrical connection between the electrical connector 10 and the corresponding accessory device 20. In one embodiment, the first conductor 16 includes multiple individual insulated conductors, and these solder joints 153 can contact each of the individual insulated conductors in the first conductor 16 to provide information about the electrical connector 10 and / or the accessory device 20 to which the electrical connector 10 is a part, or to perform other specific functions.

[0048] In summary, by combining the mechanical foolproof structure design (the foolproof port 311 structure matches the foolproof part 112 structure) and the electronic foolproof identification design (the first identification characteristic element 151 of the circuit) of the electrical connector 10, mis-insertion can be avoided through two levels of foolproof design: mechanical foolproof structure design and electronic foolproof identification design. This is achieved whether it is the mixed use of accessory devices 20 corresponding to different models of the same electronic device 30, the mixed use of different electronic devices 30 but with the same electrical connector 10, or other such scenarios. Specifically, the foolproof part 112 design on the housing 111 ensures that the user can effectively identify whether it matches the corresponding foolproof port 311 at the beginning of use. When applied to multiple models of electronic devices 30, even if the foolproof port 311 structure of many models of electronic devices 30 is the same, the plug connector 11 of the electrical connector 10 can be smoothly inserted into the socket connector 31. The first identification characteristic element 151 in the circuit can further reduce the problem of unexpected insertion. Furthermore, if the plug connector 11 of the electrical connector 10 is inserted into the socket connector 31 of an incompatible electronic device 30, the electronic device 30 may report an error, such as by displaying an error message on a mobile terminal or by issuing a voice error message to the user.

[0049] In this embodiment of the invention, the electrical connector 10 enables the coupling and electrical connection between the electronic device 30 and the corresponding accessory device 20. The anti-foolproof part 112 of the plug connector 11 of the electrical connector 10 matches the anti-foolproof opening 311 of the socket connector 31 of the electronic device 30. A circuit is also provided, which can confirm the matching with the accessory device 20 through the MCU of the electronic device 30. This avoids the risk of unpredictable damage to the plug connector 11 and socket connector 31 due to incorrect insertion. By combining the mechanical anti-foolproof structure design and the electronic anti-foolproof identification design of the electrical connector 10, the universality of the electrical connector 10 is achieved, while improving the accuracy and reliability of the fitting and insertion of the plug connector 11 of the electrical connector 10 and the socket connector 31 of the electronic device 30. This makes it safer and more convenient to use, reduces the difficulty for users to identify the electrical connector, and improves the user experience.

[0050] Optionally, continue to refer to Figure 7 and Figure 8 The first identification feature element 151 includes a first resistor.

[0051] Specifically, each electrical connector 10 corresponds to a first identification characteristic element 151, which includes a first resistor. Thus, after a mating event occurs—that is, after the plug connector 11 of the electrical connector 10 and the socket connector 31 of the electronic device 30 are electrically connected—one end of the first resistor in any electrical connector 10 can be electrically connected to the electrical contact on the tongue 312 of the socket connector 31 through the corresponding first electrical contact 1212 or second electrical contact 1222. Simultaneously, the electronic device 30 detects the first resistor through its circuitry to determine the type and model of the accessory device 20 corresponding to the electrical connector 10, thereby determining whether the electronic device 30 and the accessory device 20 are compatible. For example, the resistance value of the first resistor of the electrical connector 10 adapted to different types of electronic devices 30 can be different to distinguish the type of electronic device 30. For instance, if the electronic device 30 is a pelvic floor instrument main unit and a transcranial therapy instrument main unit, the first resistors of the two main units will be different.

[0052] In one specific embodiment, the electronic device 30 is provided with a voltage sensor. After a docking event occurs, the first resistor (first identification characteristic element 151) in the circuit enables the electronic device 30 to measure the voltage through the voltage sensor and compare it with a preset voltage threshold. If the voltage is within the voltage threshold, it indicates that it is matched.

[0053] Optionally, continue to refer to Figure 7 and Figure 8 The circuit also includes a second identification feature element 152, which is used to realize the second level of identification of the accessory device 20 by the electronic device 30 after the first level of identification is successful. It should be noted that the order in which the electronic device 30 identifies the first identification feature element 151 and the second identification feature element 152 is not limited. The first identification feature element 151 can be identified first, followed by the second identification feature element 152, or both can be identified simultaneously.

[0054] Specifically, the circuit includes both a first identification characteristic element 151 and a second identification characteristic element 152. Optionally, the first identification characteristic element includes a first resistor, and the second identification characteristic element includes a second resistor. After a docking event, the first identification characteristic element 151 in the circuit enables the electronic device 30 to perform a first-level identification of the accessory device 20, and after successful first-level identification, the second identification characteristic element 152 enables the electronic device 30 to perform a second-level identification of the accessory device 20. In a more easily understood way, the electronic device 30 can obtain the characteristic information of the first identification characteristic element 151 and the characteristic information of the second identification characteristic element 152 in the corresponding circuit to determine whether the electronic device 30 itself matches the accessory device 20 electrically connected to the electrical connector 10. For example, the electronic device 30 can store a set of characteristic information, and first compare the obtained characteristic information of the first identification characteristic element 151 with the stored set of characteristic information, and then compare the obtained characteristic information of the second identification characteristic element 152 with the stored set of characteristic information to determine whether the electronic device 30 matches the accessory device 20 electrically connected to the electrical connector 10. For example, the first identification feature element 151 and the second identification feature element 152 store feature information that matches the electronic device 30 with the accessory device 20. For different accessory devices 20, the feature information of the first identification feature element 151 and the second identification feature element 152 in the electrical connector 10 that is matched with it is different, so as to facilitate identification and differentiation.

[0055] It should be noted that in the circuit, when only the first identification characteristic element 151 is used to achieve the first level of identification of the accessory device 20 by the electronic device 30, the first identification characteristic element 151 can be a first resistor. Based on the voltage division error of the resistor value and the identification accuracy of the MCU of the electronic device 30, N voltage difference levels can be divided. That is, the electronic device 30 can identify a maximum of N accessory devices 20. It is understandable that as the required number of voltage difference levels increases, the identification accuracy of the MCU of the electronic device 30 needs to be further improved, but more precise identification is accompanied by increased costs. Therefore, in this circuit, in addition to using the first identification characteristic element 151, a second identification characteristic element 152 is also used. By classifying the accessory device 20 into first and second levels of identification, the number of accessory devices 20 that the electronic device 30 can identify can be increased. For example, when only the first identification element 151 is used, the circuit has only one identification channel, which can be divided into N=10 voltage difference levels. However, when the first identification element 151 and the second identification element 152 are used, the circuit can have two identification channels, which can be divided into N×N (i.e., 10×10) voltage difference levels. That is, the two identification channels can identify 10×10 different products. In other words, without increasing the identification accuracy of the MCU, the number of devices that the electronic device 30 can identify to the accessory device 20 can be increased exponentially by simply setting the first identification element 151 and the second identification element 152, while ensuring the identification effect and further controlling the increase in cost. On the other hand, the first identification element 151 and the second identification element 152 can be identified by the MCU of the electronic device 30. For example, the first identification element 151 can be used by the electronic device 30 to identify its corresponding electronic device category, such as identifying that accessory device 20 corresponds to accessory device 20 of the pelvic floor therapy device main unit. The second identification element 152 can be used by the same electronic device 30 to identify the differences between different accessory devices 20 it corresponds to. For example, the pelvic floor device main unit has two channels. Channel A of the pelvic floor device main unit needs to be adapted to the first type of accessory device (vaginal electrode), while channel B of the pelvic floor device main unit needs to be adapted to the second type of accessory device (abdominal monitoring electrode). The second identification element 152 used by the electrical connector 10 connected to the vaginal electrode has a resistance value of one, and the second identification element 152 used by the electrical connector 10 connected to the abdominal monitoring electrode has a resistance value of two. The resistance values ​​one and two are different. Through the above-mentioned hierarchical identification, the degree of hierarchical identification can be effectively improved, and it has a wider range of product types and versatility. For example, related devices with multiple channels, such as pelvic floor devices or beauty masks, can adopt this implementation scheme.

[0056] Optionally, continue to refer to Figures 1-8The first surface 1211 and the second surface 1221 of the wing 12 are arranged to have 180-degree symmetry.

[0057] Specifically, the flap 12 can be designed with 180-degree symmetry and bidirectional use, which allows the electrical connector 10 to be inserted into the socket connector 31 of the corresponding electronic device 30 in a first direction with the first surface 1211 facing upwards and a second direction with the first surface 1211 rotated 180 degrees downwards (at which point the second surface 1221 faces upwards). To achieve the non-directional characteristic of the electrical connector 10, the electrical connector 10 is not polarized. That is, the electrical connector 10 does not include a physical key configured to mate with the mating key in the corresponding socket connector 31, and ensures that the mating between the plug connector 11 and the socket connector 31 occurs only in a single direction. Furthermore, by way of example, the first surface 1211 of the wing 12 may also include a first contact area (not shown in the figure), and the second surface 1221 of the wing 12 may also include a second contact area (not shown in the figure). Each first electrical contact 1212 may be placed within the first contact area, and each second electrical contact 1222 may be placed within the second contact area, such that each first electrical contact 1212 in the first contact area is arranged symmetrically with each second electrical contact 1222 in the second contact area. The grounding contacts formed on the third surface (not shown in the figure) and the fourth surface (not shown in the figure) of the wing 12 may also be arranged symmetrically. This symmetrical arrangement of the electrical contacts ensures that the electrical contacts on either the first surface 1211 or the second surface 1221 of the wing 12 can be correctly aligned with the contacts in the socket connector 31, regardless of orientation.

[0058] In some embodiments, the shape of the flap 12 can be configured such that if the flap 12 is divided into upper and lower halves along a horizontal plane bisecting its center, the physical shape of the cross-section of the upper half of the flap 12 is substantially the same as the physical shape of the cross-section of the lower half. Similarly, if the flap 12 is divided into left and right halves along a vertical plane bisecting its center, the physical shape of the cross-section of the left half of the flap 12 is substantially the same as the physical shape of the cross-section of the right half. In other bidirectional embodiments, the cross-sectional shape of the flap 12 need not be perfectly symmetrical, as long as the electrical connector 10 does not include a key that prevents the plug connector 11 from being inserted into the corresponding socket connector 31 in two different directions and the electrical contacts are correctly aligned with the electrical contacts in the corresponding socket connector 31 in either direction.

[0059] In one specific implementation, Figure 3 , Figure 5 and Figure 7 The structure of the wing 12 shown is a Type-C interface. Figure 4 , Figure 6The structure of the wing 12 shown in the figure is a Lightning interface. This embodiment is only an example and is not intended to limit the design. Of course, the structure of the wing 12 can also be adapted and fabricated by those skilled in the art. On the one hand, when applied to a Type-C interface or a Lightning interface, the formed electrical connector 10 can achieve bidirectional insertion and mating. That is, the formed electrical connector 10 can be mated and electrically connected with the socket connector 31 of the corresponding electronic device 30 in both positive and negative orientations. One orientation can be understood as the other orientation rotated 180 degrees along the axis of symmetry. In other words, the outer surface structure of the plug connector 11 of such an electrical connector 10 can provide a connection locking function when mating the socket, and generally does not have other additional functional attributes. On the other hand, the first electrical contact 1212 and the second electrical contact 1222 in such an electrical connector 10 are designated to transmit specific types of signals, such as power, data, etc.

[0060] In addition to the 180-degree symmetrical, bidirectional design, the flaps 12 of the plug connector 11 in this embodiment can also be configured such that each first electrical contact 1212 formed on the first surface 1211 of the flap 12 is electrically connected to each second electrical contact 1222 formed on the second surface 1221. That is, in some embodiments, each first electrical contact 1212 in the first contact area is electrically connected to a corresponding second electrical contact 1222 in the second contact area. In this way, each given signal to be transmitted by the plug connector 11 will be sent through either the first electrical contact 1212 or the second electrical contact 1222. Thus, compared to the electrical contacts formed on the first surface 1211 and the second surface 1221 of the wing 12 being electrically insulated from each other and assigned to different signals, the number of different signals that a given number of electrical contacts can transmit is reduced by half. However, the corresponding socket connector 31 only needs to have electrical contacts on one surface within its cavity (e.g., the top or bottom surface). As a result, the socket connector 31 in this embodiment can be manufactured to be thinner than a socket connector 31 that has electrical contacts on both the top and bottom surfaces within its cavity. This, in turn, allows the electronic device 30 that houses the socket connector 31 to also be thinner, which is beneficial for achieving miniaturized and lightweight designs.

[0061] Optionally, continue to refer to Figures 1-8 The foolproof part 112 has a foolproof surface that is 180 degrees symmetrical along the mating direction, so that the plug connector 11 can be inserted into the foolproof hole 311 in either of the two mating directions.

[0062] Specifically, the mating direction can be understood as a direction parallel to the length of the housing 111. For example, the mating direction can be understood as two directions, one positive and one negative. The foolproof part 112 can be designed with 180-degree symmetry and bidirectional use, allowing the plug connector 11 of the electrical connector 10 to be inserted into the foolproof port 311 in either of the two mating directions. In other words, the plug connector 11 of the electrical connector 10 can be inserted into the foolproof port 311 in one mating direction, and after rotating 180 degrees, it can still be inserted into the foolproof port 311 in the other mating direction. It is understood that the structure of the foolproof port 311 can be set according to the structure of the corresponding foolproof part 112 to ensure that the two can match to achieve the electrical connection between the plug connector 11 and the socket connector 31.

[0063] In some embodiments, the shape of the foolproof part 112 can be formed such that if the foolproof part 112 is divided into upper and lower halves along a horizontal plane that bisects its center, the physical shape of the cross-section of the upper half of the foolproof part 112 is substantially the same as the physical shape of the cross-section of the lower half. Similarly, if the foolproof part 112 is divided into left and right halves along a vertical plane that bisects its center, the physical shape of the cross-section of the left half of the foolproof part 112 is substantially the same as the physical shape of the cross-section of the right half. In other bidirectional embodiments, the cross-sectional shape of the foolproof part 112 does not need to be perfectly symmetrical, as long as the electrical connector 10 does not include a key that prevents the plug connector 11 from being inserted into the corresponding socket connector 31 in two different directions and the electrical contacts are correctly aligned with the electrical contacts in the corresponding socket connector 31 in either direction.

[0064] Optionally, continue to refer to Figure 7 and Figure 8 The first identification feature element 151 includes at least one chip that can be used to store information. The chip stores at least two sets of identification information, namely the first identification information and the second identification information. After the docking event, the circuit acquires the first identification information and the second identification information through the MCU of the electronic device 30, and realizes the first level and the second level identification of the accessory device 20. It should be noted that the order in which the electronic device 30 identifies the first identification information and the second identification information is not limited. The first identification information can be identified first and then the second identification information can be identified, or both can be identified at the same time.

[0065] Specifically, each electrical connector 10 corresponds to a first identification feature element 151, which is a chip. For example, this chip can be a read / write memory, storing identification information such as serial numbers that can be used for verification and identification. The chip can store at least two sets of identification information, including first identification information and second identification information. After a docking event occurs, the electronic device 30 can identify the accessory device 20 through at least two sets of identification information on the circuit. For example, the first identification information and the second identification information are respectively the type information of the electronic device 30 corresponding to the accessory device 20 and the model information of the accessory device 20 itself. After a docking event occurs, the electronic device 30 obtains the above information through the circuit and determines whether the accessory device 20 electrically connected to the electrical connector 10 is compatible with the device. Furthermore, the chip may store multiple different pieces of information to enable the electronic device 30 to achieve multi-level identification.

[0066] Furthermore, it is understood that the first identification feature element 151 may also be other electronic devices with readable features, so that the electronic device 30 can perform multi-level identification of the corresponding accessory device 20.

[0067] This embodiment provides several examples of error-proof identification for possible application scenarios of electronic devices, electrical connectors, and accessory devices. Of course, there are other application scenarios, which will not be listed in this embodiment. The examples are as follows:

[0068] In a specific application scenario, the main unit (i.e., electronic device 30) of the phototherapy beauty mask has only one socket connector 31. However, this phototherapy beauty mask has two configurations, high and low. Both the high and low configuration main units 30 (P1 and P2) need to be matched with their respective accessory devices 20 (U1 and U2) to be used normally. However, the two accessory devices 20 (U1 and U2) have the same external structure (i.e., the anti-foolproof part 112 has the same configuration). That is, the two accessory devices 20 can be structurally plugged into different main units (P1 and P2). When a user has multiple devices of the above two models at the same time, identification problems will occur in daily use.

[0069] Option 1: Each of the electrical connectors 10 that connect U1 and U2 is equipped with a first identification characteristic element 151 with a different resistance value. When the user mistakenly connects U1 (accessory device 20) to P2 (electronic device 30), an error will be reported because the identified voltage does not match the preset voltage value. The error report may include a display or voice error report from the mobile terminal (the mobile terminal is in communication connection with the host device).

[0070] Option 2: Each electrical connector 10 connected to U1 and U2 is equipped with two resistors. The first identification element 151 and the second identification element 152 in U1 have resistance values ​​one and two, respectively. The first identification element 151 and the second identification element 152 in U2 have resistance values ​​three and four, respectively. Resistance values ​​one and three are the same, while resistance values ​​two and four are different. When a user mistakenly connects U1 (accessory device 20) to P2 (electronic device 30), P2 will detect the resistance value one corresponding to the first identification element 151. For products like phototherapy beauty masks, the second identification feature element 152 is then identified. It should be noted that even if the information of the first identification feature element 151 identified here is correct, it can only be judged by the electronic device 30 as belonging to the accessory device 20 used in the same type as the phototherapy beauty mask, and cannot prove that it can definitely be used in the current model of electronic device 30 (P2). Then, because the voltage of the second resistance value of U1 is not matched with the preset voltage value, an error is reported. The error report may include the display or voice error of the mobile terminal (the mobile terminal is connected to the host device).

[0071] In another specific application scenario, the main unit (i.e., electronic device 30) of the pelvic floor device has only one socket connector 31. Users can purchase two identical accessory devices 20 (i.e., vaginal electrodes) that are compatible with it, so that user one and user two can share the same electronic device 30. User one can use the electronic device 30 to bind the account information of vaginal electrode one (accessory device 20), and user two can also use the electronic device 30 to bind the account information of vaginal electrode two (accessory device 20). Vaginal electrode one has a first identification characteristic element 151 and a second identification characteristic element 152, wherein the first identification characteristic element 151 is a resistor and the second identification characteristic element 152 is a memory. When binding account information, a set of unique information of user one, such as identity information, is recorded. Vaginal electrode two has the same resistance value of the first identification characteristic element 151 as vaginal electrode one, and a set of unique information of user two is recorded when binding account information. In this way, when user 1 mistakenly inserts vaginal electrode 2 into electronic device 30, although the first identification feature element 151 can identify it, the information recorded by the second identification feature element 152 cannot match user 2's account, and the host device will report an error. The error may be displayed on the mobile terminal or reported by voice.

[0072] In another specific application scenario, phototherapy beauty masks and transcranial therapy devices are two completely different types of medical devices. For example, the main devices (i.e., electronic devices 30) of phototherapy beauty masks and transcranial therapy devices have different designs for their respective electrical connectors 10 with different anti-misfit configurations 112, which can effectively prevent mis-insertion.

[0073] In another specific application scenario, phototherapy beauty masks and transcranial therapy devices belong to two completely different types of medical devices. For example, the main unit of the phototherapy beauty mask (i.e., electronic device 30) and the main unit of the transcranial therapy device each have a socket connector 31, and both are compatible with accessory devices 20 of the same shape (e.g.,...). Figure 9 The abdominal monitoring electrodes shown are identical to those of the electrical connector 10, and the foolproof design of the connector 10's 112 is also identical. Because the accessory device 20 uses the same shape, there is a possibility of users inserting the wrong device. Since the phototherapy beauty mask and the transcranial therapy device each have different first identification characteristic elements 151 (resistors), if a user incorrectly inserts the accessory device 20 into the main unit, an error will occur because the identified voltage does not match the preset voltage value. The error may include a display or voice error message from the mobile terminal (the mobile terminal is connected to the main unit).

[0074] Based on the same concept, this utility model also provides an electrical connector kit that provides a communication path between electronic devices and accessory devices. Figure 9 This is a structural diagram of an accessory device (abdominal monitoring electrode) for the first type of electrical connector. Figure 10 It is an accessory device that electrically connects to another type of electrical connector (vaginal electrode). Figure 11 It is used for Figure 9 and Figure 10 The diagram shows the structure of the electronic device to which the electrical connector is adapted. Figure 12 yes Figure 11 A perspective view of the socket connector of the electronic device shown; as follows: Figures 9-12 As shown, the electronic device 30 has at least two receptacle connectors 31, each receptacle connector 31 having a keying notch 311. The electrical connector kit includes electrical connectors 10 adapted to the number of receptacle connectors 31 (the specific structure of the electrical connectors 10 can be found in [reference]). Figures 1-10Each electrical connector 10 has one end electrically connected to a corresponding accessory device 20, and the other end has a plug connector 11 adapted to a socket connector 31. Each plug connector 11 includes a housing 111 and a flap 12. The housing 111 has a foolproof part 112 extending along its outer surface and corresponding to a foolproof notch 311. The foolproof part 112 is inserted into and pressed against the foolproof notch 311 in the mating direction to achieve a mating event. The flap 12 has a first surface 1211 and a second surface 1221. A plurality of first electrical contacts 1212 are carried on the first surface 1211 of the flap 12, and on the second surface 1221 of the flap 12. The connector 10 includes a plurality of second electrical contacts 1222, each of the plurality of first electrical contacts 1212 being electrically connected within the wing 12 or housing 111 to each corresponding electrical contact among the plurality of second electrical contacts 1222; the connector 10 also includes a circuit coupled to at least a portion of the plurality of first electrical contacts 1212 and at least a portion of the plurality of second electrical contacts 1222, the circuit including a first identification feature element 151 and used to enable the electronic device 30 to identify the accessory device 20 at a first level via the first identification feature element 151 after a docking event; wherein the configuration of the foolproof part 112 of any plug connector 11 is different.

[0075] First, it should be noted that in this embodiment, the electronic device 30 is limited to having at least two socket connectors 31, each socket connector 31 having a foolproof notch 311, and the electrical connector kit including electrical connectors 10 adapted to the number of socket connectors 31, each electrical connector 10 having a plug connector 11 at one end adapted to the socket connectors 31, and the configuration of the foolproof notch 112 of any plug connector 11 being different. Figure 11 and Figure 12 Taking an example, the electronic device 30 has two socket connectors 31, and the corresponding electrical connector kit should also have two plug connectors 11. The two socket connectors 31 correspond to different application scenarios or different types of accessory devices 20. If the structures of the keying ports 311 corresponding to the two socket connectors 31 are the same, the plug connector 11 adapted to the left socket connector 31 may be mistakenly inserted into the right socket connector 31, and similarly, the plug connector 11 adapted to the right socket connector 31 may be mistakenly inserted into the left socket connector 31. This kind of incorrect insertion is an unintended usage error, which may not only increase the risk of equipment damage but also further increase the user's identification cost when using the product. Therefore, for any electronic device 30 with at least two socket connectors 31, it is necessary to limit the structure of the keying ports 311 corresponding to each socket connector 31 to be different. Accordingly, the configuration of the keying part 112 corresponding to each keying port 311 with a different structure is also different, effectively avoiding the problem of misuse of multiple electrical connectors 10 corresponding to the same electronic device 30.

[0076] Specifically, please refer to Figure 9 and Figure 10 , Figure 9 The accessory equipment shown Figure 10 The accessory devices shown are all plugged in simultaneously for use with Figure 11 The host device (i.e., electronic device 30) can be adapted to be plugged into the socket connector 31 in the electronic device 30. The connectors of the two have the following characteristics: Figure 1 and Figure 2 The different types of electrical connectors 10 in the text are as follows: Figure 9 The corresponding connector 10 of China Electric Figure 1 The error-proof part 112 and Figure 10 The corresponding connector 10 of China Electric Figure 2 The configuration of the error-proof part 112 is different, and it is adapted to it. Figure 11 and Figure 12 The anti-misfit port 311 in the middle has a differentiated design. During docking, the differentiated anti-misfit port 311 and anti-misfit part 112 design can effectively avoid unexpected incorrect insertion.

[0077] For example, Figure 11 This refers to the main unit (i.e., electronic device 30) of the pelvic floor instrument. Figure 9 To be compatible with plug-in Figure 11 Abdominal monitoring electrode of electronic device 30 Figure 10 To be compatible with plug-in Figure 11 Before use, the user correctly inserts the electrical connector of the abdominal monitoring electrode into one socket connector 31 of the electronic device 30 via the plug connector 11, and correctly inserts the electrical connector of the vaginal electrode into the other socket connector 31 of the electronic device 30 via its plug connector 11. The abdominal monitoring electrode (accessory device 20) has a first flexible electrode piece 21 and a second flexible electrode piece 22, which are connected to a splitter 23 via a second wire 211 and a third wire 221, respectively. The other end of the splitter 23 is electrically connected to its electrical connector 10 via a first wire 16. Similarly, the vaginal electrode (accessory device 20) has an electrode body 24 and a first metal electrode piece 241 and a second metal electrode piece 242 disposed on both sides of the electrode body 24. The electrode body 24 is connected to the splitter 23 via a fourth wire 25, and the other end of the splitter 23 is electrically connected to its electrical connector 10 via a wire 16. Here, Figure 9 Electrical connector 10 and Figure 10 The electrical connector 10 in the middle needs to be synchronously connected to Figure 11On the electronic device 30, the two electrical connectors 10 belong to the same electrical connector kit and have different foolproof designs 112. The identification information contained in the circuitry of each plug connector 11 of the two electrical connectors 10 is also different. The structure of any electrical connector 10 in the electrical connector kit can adopt the description and explanation of the electrical connector 10 of any of the above embodiments, and the structures of the housing 111 and the wing 12 included in each plug connector 11 can be the same or different, as long as the mating event between the plug connector 11 and the socket connector 31 can be realized, all are within the protection scope of this embodiment. Furthermore, in addition to the socket connector 31 used for electrical connection with the accessory device 20, the electronic device 30 also includes a power supply port 32 so that the electronic device 30 can maintain normal operation when powered externally.

[0078] Continue to refer to Figures 1-6 The plug connector 11 includes a housing 111 and a flap 12. Exemplarily, the housing 111 is typically a structure that a user holds when inserting or removing the electrical connector 10 from the corresponding receptacle connector 31. Exemplarily, the housing 111 may be made of a dielectric material. Exemplarily, the housing 111 may have a generally rectangular cross-section, or it may have a rectangular cross-section with rounded or angled edges, a circular cross-section, an elliptical cross-section, and many other suitable shapes. The flap 12 can be understood as a portion extending longitudinally away from the housing 111 along the mating direction (or along a direction parallel to the length of the housing 111). In the mating direction, one end of the housing 111 is the fixedly connected flap 12, and the other end of the housing 111 is the fixedly connected first wire 16. That is, one end of the plug connector 11 achieves electrical connection with the receptacle connector 31 of the corresponding electronic device 30 via the flap 12, and the other end of the plug connector 11 achieves electrical connection with the corresponding accessory device 20 via the first wire 16. Although... Figure 1 and Figure 3 As not shown, a portion of the structure of the wing 12 and a portion of the structure of the first wire 16 may extend within and be surrounded by the housing 111. Furthermore, by way of example, the wing 12 may be made of various materials including metals, dielectrics, or combinations thereof.

[0079] Furthermore, the dimensions of the wing 12 are designed to be inserted into the socket connector 31 of the corresponding electronic device 30 during a docking event. The wing 12 has a first surface 1211 and a second surface 1221 that are parallel (or approximately parallel) and correspondingly arranged. A plurality of first electrical contacts 1212 are carried on the first surface 1211 of the wing 12, and a plurality of second electrical contacts 1222 are carried on the second surface 1221 of the wing 12. Exemplarily, the number of first electrical contacts 1212 is the same as the number of second electrical contacts 1222, and the orthographic projections of the first electrical contacts 1212 on the first surface 1211 and the orthographic projections of the second electrical contacts 1222 on the first surface 1211 correspond one-to-one and overlap. Exemplarily, these electrical contacts can be classified as data contact points. Exemplarily, the shapes of the first electrical contacts 1212 and the second electrical contacts 1222 can be square, circular, leaf spring, or cantilever beam, etc. This embodiment is merely an example and is not limited thereto. Exemplarily, in one specific embodiment, Figure 5 and Figure 7 Each of the first electrical contacts 1212 shown is located on the same side of the first surface 1211, and each of the first electrical contacts 1212 is located on the side of the first surface 1211 closer to the second surface 1221. Similarly, each of the second electrical contacts 1222 is located on the same side of the second surface 1221, and each of the second electrical contacts 1222 is located on the side of the second surface 1221 closer to the first surface 1211. In another specific embodiment, Figure 4 and Figure 6 Each of the first electrical contacts 1212 shown is located on the same side of the first surface 1211, and each of the first electrical contacts 1212 is located on the side of the first surface 1211 away from the second surface 1221. Each of the second electrical contacts 1222 is located on the same side of the second surface 1221, and each of the second electrical contacts 1222 is located on the side of the second surface 1221 away from the first surface 1211.

[0080] These electrical contacts may be raised, recessed, or flush with the outer or inner surface of the flap 12, and each of the plurality of first electrical contacts 1212 is electrically connected within the flap 12 or housing 111 to each corresponding contact of the plurality of second electrical contacts 1222, such that when the flap 12 is inserted into the corresponding socket connector 31, these electrical contacts can be electrically coupled to the corresponding electrical contacts in the socket connector 31 to facilitate a communication electrical connection between the electrical connector 10 and the electronic device 30. In some embodiments, these electrical contacts may be self-cleaning wiping contacts, which, after initially contacting the corresponding electrical contacts in the socket connector 31 during a mating event, further slide across the electrical contacts in the socket connector 31 by a wiping motion before reaching the final desired contact position. Exemplarily, these electrical contacts may be made of copper, nickel, brass, stainless steel, metal alloys, or any other suitable conductive material or combination of conductive materials. For example, a first electrical contact 1212 can be printed on the first surface 1211 of the flap 12, and a second electrical contact 1222 can be printed on the second surface 1221 of the flap 12, using a technique similar to that used for printing contacts on a printed circuit board. For example, these electrical contacts can be formed by imprinting from a lead frame, which is located on the first surface 1211 and the second surface 1221 of the flap 12, respectively, and is surrounded by a dielectric material.

[0081] In other embodiments, one or more grounding contacts may also be formed on the third (illustrated) and fourth (illustrated) surfaces of the flap 12, wherein the third surface of the flap 12 can be understood as one side connecting the first surface 1211 and the second surface 1221, and the fourth surface of the flap 12 can be understood as the other side connecting the first surface 1211 and the second surface 1221. Each of these grounding contacts may be formed on the exterior of its respective side surface, or constitute part of the exterior of its respective side surface. Exemplarily, these grounding contacts may be formed within pockets, indentations, cuts, or similar recesses formed on each of the third and fourth surfaces of the flap 12, and / or these grounding contacts may be formed as part of pockets, indentations, cuts, or similar recesses formed on each of the third and fourth surfaces of the flap 12, as detailed below, whereby the formed pockets, indentations, cuts, or similar recesses may operatively engage with a retaining mechanism in the corresponding socket connector 31.

[0082] like Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 The electrical connectors 10 shown all include circuitry, but Figure 7 The first surface 1211 and the second surface 1221 of the wing 12 shown are the inner surfaces of the upper and lower surfaces of the wing 12. Figure 8 The first surface 1211 and the second surface 1221 of the wing 12 shown are the outer surfaces of the upper and lower surfaces of the wing 12. In one specific embodiment, Figure 3 , Figure 5 and Figure 7 The structure of the winglet 12 shown can be a Type-C interface. Figure 4 , Figure 6 and Figure 8 The wing 12 structure shown can be a Lightning interface. The common feature of the two wing 12 structures is that they can be plugged in and out in both directions. This embodiment is only an example and is not limited. Of course, the structure of the wing 12 can also be adapted and prepared by those skilled in the art.

[0083] The circuit in the electrical connector 10 can be coupled to at least a portion of the plurality of first electrical contacts 1212 and at least a portion of the plurality of second electrical contacts 1222. In other words, the first electrical contacts 1212 on the first surface 1211 of the wing 12 can be electrically connected to the corresponding second electrical contacts 1222 on the second surface 1221 of the wing 12 through the circuit. Thus, the socket connector 31 of the electronic device 30 can be electrically connected via the first electrical contacts 1212 or the second electrical contacts 1222, and obtain the characteristic information of the circuit, such as relevant identifiers, serial numbers, models, manufacturer IDs, etc. In one specific embodiment, the circuit includes a first identification characteristic element 151, which can be used to achieve a first-level identification of the accessory device 20 by the electronic device 30 after a docking event. More easily understood, the electronic device 30 can obtain the characteristic information of the first identification characteristic element 151 in the corresponding circuit to determine whether the electronic device 30 itself is compatible with the accessory device 20 electrically connected to the electrical connector 10. For example, the electronic device 30 may store a set of characteristic information, and compare the acquired characteristic information with the stored set of characteristic information to determine whether the electronic device 30 itself matches the accessory device 20 electrically connected to the electrical connector 10. For example, the circuit and the first identification characteristic element 151 store characteristic information indicating that the electronic device 30 matches the accessory device 20. For different accessory devices 20, the characteristic information of the circuit and the first identification characteristic element 151 in the corresponding electrically connected electrical connector 10 is different, so as to more accurately and quickly identify the matching relationship. For example, the circuit and the first identification characteristic element 151 may be a single circuit element, a small integrated circuit, etc.

[0084] In addition, continue to refer to Figure 7 and Figure 8 , Figure 7 and Figure 8 The electrical connectors 10 shown all include circuitry, which can be specifically embodied in their carrier (PCB circuit board 15). A first identification feature element 151 is disposed on the PCB circuit board 15. The PCB circuit board 15 may also include solder joints 153, which can be electrically connected to the first conductor 16, thereby realizing the electrical connection between the electrical connector 10 and the corresponding accessory device 20. In one embodiment, the first conductor 16 includes multiple individual insulated conductors, and these solder joints 153 can contact each of the individual insulated conductors in the first conductor 16 to provide information about the electrical connector 10 and / or the accessory device 20 to which the electrical connector 10 is a part, or to perform other specific functions.

[0085] The specific structure of any one of the electrical connectors in the electrical connector kit is described below. Please refer to the above embodiments for relevant details, which will not be repeated here.

[0086] Optionally, continue to refer to Figures 1-12 The circuit also includes a second identification feature element 152, which is used to enable the electronic device 30 to identify the accessory device 20 at the second level after the first level of identification is successful.

[0087] For specific details, please refer to the above embodiments, which will not be repeated here.

[0088] Optionally, continue to refer to Figures 1-12 The first identification feature element 151 includes a first resistor; the resistance value of the first resistor in each electrical connector 10 in the electrical connector kit is the same.

[0089] Specifically, in this embodiment, the resistance value of the first resistor of each electrical connector 10 is set to be the same. The identification of the resistance value of the first resistor of the electrical connector 10 can be used by the electronic device 30 to identify its corresponding electronic device category. For example, it can identify that the accessory device 20 corresponds to the accessory device 20 corresponding to the pelvic floor therapy instrument host.

[0090] Optionally, continue to refer to Figures 1-12 The second identification feature element 152 includes a second resistor; the resistance value of the second resistor in each electrical connector 10 in the electrical connector kit is different.

[0091] Specifically, in this embodiment, the resistance value of the second resistor in each electrical connector 10 is different. Therefore, the identification of the resistance value of the second resistor in the electrical connector 10 can be used to identify the differences between different accessory devices 20 used by the same electronic device 30. Furthermore, in one specific embodiment, after a docking event, the first resistor in the first identification characteristic element 151 on the circuit enables the electronic device 30 to identify the accessory device 20 at a first level. After successful identification at the first level, the second resistor in the second identification characteristic element 152 enables the electronic device 30 to identify the accessory device 20 at a second level. This hierarchical identification effectively improves the degree of hierarchical identification and has broader applicability to various product types. For example, multi-channel devices such as pelvic floor devices or beauty masks can adopt this implementation scheme.

[0092] Optionally, continue to refer to Figures 1-12 The first surface 1211 and the second surface 1221 of the wing 12 are arranged to have 180-degree symmetry.

[0093] Optionally, continue to refer to Figures 1-12 The foolproof part 112 has a foolproof surface that is 180 degrees symmetrical along the mating direction, so that the plug connector 11 of the electrical connector 10 can be inserted into the foolproof hole 311 in either of the two mating directions.

[0094] For specific details, please refer to the above embodiments, which will not be repeated here.

[0095] Optionally, continue to refer to Figures 1-12 The first identification feature element 151 includes at least one chip that can be used to store information. The chip stores at least two different sets of identification information. The circuit is used to achieve hierarchical identification of the electronic device 30 to the accessory device 20 by the two sets of identification information after a docking event.

[0096] Specifically, each electrical connector 10 corresponds to a first identification feature element 151, which is a chip. For example, this chip can be a read / write memory, storing identification information such as serial numbers that can be used for verification and identification. Any chip in the first identification feature element 151 can store at least two different sets of identification information. After a docking event occurs, the electronic device 30 can identify the accessory device 20 through at least two sets of identification information on the circuit. For example, any chip in the first identification feature element 151 stores first identification information and second identification information. The circuit is used to achieve a first-level identification of the accessory device 20 by the electronic device 30 through the first identification information after a docking event, and to achieve a second-level identification of the accessory device 20 by the electronic device 30 through the second identification information after successful first-level identification. Optionally, the first identification information and the second identification information are different; the first identification information and the second identification information are respectively the type information of the electronic device 30 corresponding to the accessory device 20 and the model information of the accessory device 20 itself. In this way, hierarchical identification of the accessory device 20 by the electronic device 30 is achieved.

[0097] This embodiment provides several examples of error-proof identification for possible application scenarios of electronic devices, electrical connectors, and accessory devices. Of course, there are other application scenarios, which will not be listed in this embodiment. The examples are as follows:

[0098] In a specific application scenario, a home-use medical electronic device has at least two socket connectors 31 to connect two accessory devices F1 and F2, respectively, for example, accessory device F1 operates externally and accessory device F2 operates internally. Since the keying opening 311 structures of the two socket connectors 31 corresponding to accessory devices F1 and F2 are different, the keying portion 112 configurations of the two plug connectors 11 in the corresponding electrical connector kit are also different to ensure that accessory devices F1 and F2 are not mistakenly inserted into their respective socket connectors 31.

[0099] As shown below, this embodiment also provides specific products of electronic devices, electrical connectors, and accessory devices, as well as the resistance value settings of the first resistor and the second resistor. Table 1 is a schematic table of the device products, foolproof configurations, and resistance values ​​of the first resistor and the second resistor provided in this utility model embodiment. As shown in Table 1, three types of products are used as examples for illustration.

[0100]

[0101] Table 1

[0102] Referring to Table 1, the electronic device of the phototherapy beauty host includes an interface with a socket connector for two channel lines. The mask channel line and the eyelid patch channel line can optionally share one interface, therefore their structural anti-mistake configurations are identical, both being configuration X. The neck-chest channel line has a structural anti-mistake configuration of Y. In one usage scenario, the user can connect the electronic device using the mask channel line and the neck-chest channel line separately to achieve simultaneous phototherapy treatment of the face and neck. The user can also connect the electronic device using the eyelid patch channel line and the neck-chest channel line separately to achieve simultaneous phototherapy treatment of the eyelids and neck. The user can also connect only one of the mask channel line, eyelid patch channel line, or neck-chest channel line individually. The electronic device of the transcranial therapy host includes an interface with a socket connector for one channel line. The electronic equipment of the pelvic floor unit can be continuously upgraded, including multiple generations of products. It includes an interface with a socket connector with two channel lines. For the electronic equipment of different generations of pelvic floor instruments, the structural foolproof configuration corresponding to the A-port channel line is the same, and the structural foolproof configuration corresponding to the B-port channel line is the same. However, the structural foolproof configuration corresponding to the A-port channel line is different from that corresponding to the B-port channel line.

[0103] To more quickly and accurately distinguish the above-mentioned product categories and multiple generations of similar products, it is evident that: 1) the structural anti-misalignment configurations of different types of electronic devices can vary, avoiding cross-category interoperability issues; 2) electronic devices of the same type have at least two different structural anti-misalignment configurations, and further distinguish them by the first and second resistors; 3) even if different types of electronic devices use interchangeable anti-misalignment structures (not shown in Table 1), their type can still be identified by the resistance value of the first resistor, for example, the main unit of a phototherapy facial mask and the main unit of a transcranial therapy device. Both the first-generation and second-generation pelvic floor instrument main units have a channel line with the same foolproof design. However, since their respective first resistances are 5kΩ, 4kΩ and 7kΩ, it can be seen that the first resistance can be used to identify the specific type of electronic device. 4) For electronic devices of the same type, different types of channel lines have the same foolproof design. After the first resistance value is successfully identified, the resistance value of the second resistance can be used to identify which type of channel line it belongs to. For example, the same type of channel line of the first-generation and second-generation pelvic floor instrument main units can be plugged into each other, but due to the difference in the second resistance, it can be identified whether they can be used normally.

[0104] Therefore, it is evident that different mis-proofing configurations can initially identify whether electronic devices and electrical connectors can be correctly inserted, reducing the user's cost of incorrect insertion. Furthermore, the significance of the first and second identification elements lies in the fact that even if the electronic device and electrical connector can be correctly inserted, further verification of correct connection and compatibility is necessary to ensure the normal operation of the electronic device and its corresponding accessories. Consequently, manufacturers can design electrical connectors with the same mis-proofing configuration but different electronic mis-proofing features, or they can design connectors with incompatible mis-proofing configurations while also possessing electronic mis-proofing. This allows for a high degree of standardization in the product line of such accessories, effectively improving product design consistency while further reducing R&D, design, and production costs.
